Halo PC/Mac tip details

Gephyrophobia - Good spot for the flag carrier to hide in.

Say, you're playing CTF and a teammate has the flag, but an enemy has your flag. You could have your flag carrier hide on a little ledge below the bridge by the two tunnels. To get there, use a plasma grenade and then jump and you should land on the little ledge. If you want to get out, I guess you could try to use a grenade to get the flag back to the lower level of the bridge, but it can be very risky and result in it falling. And no, I have not tested it yet. I will soon, though.
